Exhaust and 2WheelDyno Flash Tune

I have the hindle exhaust and a 2wdw flash. My brothers bike is identical to mine but all stock. There is absolutely no difference in power. My brother weighs 80 lbs more than I do and the bikes stayed side by side in a all out race between us. Mine sounds much better though, but the performance gains for the money are not worth it IMO.

Only option would be #3 my brother and I definitely equal in a straight highway run! And his was a us model.

I live all the way across the country from Nels, so I have to live with the mail order tune.

Removing stock exhaust and installing new will be pretty straight forward. I have the M4 3/4 exhaust with both stock O2 sensors removed. Although, I do have the FTECU Activetune O2 sensor plugged into the 18mm bung.

O2 bung plugs:
These plugs are kind of pricey for what they are, but I know they fit. I think any 12x1.25 stainless bolts should work.

O2 electrical connector plugs:
Here is another thread where folks discussed installing electrical plugs after removing stock O2 sensors. I think there might be other threads on this board for this topic too.  Also, there's probably a plug available to use for the AIS connector if you decide to remove that  fz10.org/thread/522/electrical-plug-fz-sensor-connector


You can have AIS turned off in the flash. I think some folks leave AIS installed and just plug the airway between airbox and AIS. I went ahead and removed AIS, turned AIS off in the flash, plugged airway, and installed Graves blockoff plates. Here's a really helpful video (useful for any work that needs the gas tank/airbox removed):



I've had mine flashed for ~2k miles, including a trackday at COTA. So, not very long. I would rate it as one of my favorite mods, but it has certainly cost a lot of time, some headaches, and >$700 to get it right. I really think Yamaha should have just shipped it like this. Instead, they give us the below neutered throttle map:

This has been brought up before. Nels says if you leave them hooked up it causes a conflict in the tune. Even though they are turned off the pcm still tries to use them. That was the last I read on here about that. Every bike is different, to actually achieve more power on your bike, it should be tuned on the Dyno. Some bikes respond well to a preset mail order tune some don't.

completey agree! Had a good in-depth conversation yesterday with them. Answered all my questions and he said if I had anymore, to just give them another call.

It's not just about more power, an ECU flash does many things for the bike. It smoothes out the throttle which makes for more predictable control, it helps the bike run cooler which is never a bad thing on anything mechanical and puts in place a fuel map that's far better than the default fuel mapping. And turns off the things that in reality are only there to help it meet certain emissions regulations but don't serve the bike or the rider well at all. Even a 100% stock bike would see gains from an ECU flash.


As for rider training, aside from basic rider training courses, large portions of the US don't have access to advanced rider course, racing courses, stunt courses etc. My only options in my area are basic and advanced rider courses (I've done both) which consist of 100% of low-speed maneuvering and bike control, which really doesn't provide a lot of real-world application outside of some general technics because if you're riding there is a very high chance you're traveling at more than 15mph. And even those courses were from a Harley dealer which in many ways feels like more of a Harley sales experience rather than advanced riding information.

$300 - $1800 for an ECU flash or Exhaust system + Flash is sometimes the only option we really have to increase performance or unlock the bikes hidden potential, not everyone has a life that allows for a cross country trip to a place that offers better rider training.

In the end, it's our bikes and our choices on what we want out of the bike we bought. For me, well I pick up my MT-10 Friday and within the next week I'm going to put the Akra 3/4 exhaust on and send my ECU to 2WDW for a flash and ordering a Corbin seat, because thats exactly what I want out of my new ride. Does the MT-10 NEED this? No, it works fine stock, but will it work BETTER with it... Yes!

The FZ10 is awesome, no doubt about that and I too ride mostly in standard mode to help smooth the throttle out as you mention. I also have a slip on Arrow that does sound nice as well. My bike is out of Yamaha warranty now, main reason why I left it alone for the most part. Now, I guess I just want to change it up a bit. I like the look of the low slung M4, I think it really adds to the whole naked street fighter look the FZ gives off. I do not have access to any sort of track to practice, nor is it really feasible to take my bike on a 2 day riding camp as you mentioned. My practice is actually riding on the street everyday. My FZ is my “fun” bike that I do not ride all the time. I ride my FJ09 everyday to work unless it’s down pouring or snow is on the ground. So this is merely an experience and learning thing for me as far as ECU flashing and exhaust goes. Anyways,I appreciate the input and advice!

Without a doubt, rider mod trumps anything we can bolt/flash onto our bikes.
